How do you build a select using formbuilder,formgroup in angular 2?
Currently what I thought of is having a option with *ngFor that loops through a list that I have created and than when an option is selected it updates the FormControl with the value that i got in my select.
HTML
<form [formGroup]="myForm" (ngSubmit)="submit()">
<select class="form-control" >
<option *ngFor="let pos of tabpositing" formControlName="tabposition" [value]="pos.name">{{pos.name}}</option>
</select>
</form>
<div style=" height: 150px; overflow: scroll;">
<pre><code>{{ myForm?.value | json }}</code></pre></div>
<div style=" height: 150px; overflow: scroll;">
<pre> {{ widget | json }}</pre>
</div>
TS
public tabpositing: any = [
{name: 'top', value: false},
{name: 'right',value: false},
{name: 'bottom',value: false},
{name: 'left',value: false}
]
constructor(public _fb: FormBuilder) { }
this.myForm = this._fb.group({
tabposition: new FormControl(''),
}),
Other option I thought is having a function that runs through a loop and created the formControl etc, but could not figure out how to get the HTML for the select
let tabpos : FormArray = new FormArray([]);
for (let i = 0; i < this.tabposition.length; i++) {
let fg = new FormGroup({});
fg.addControl(this.tabposition[i].name, new FormControl(this.tabposition[i].value))
tabpos.push(fg)
}
this.myForm = this._fb.group({
tabposition: tabpos
});
